About Synergy Aesthetics Sonoma

What is Synergy Aesthetics Sonoma?

Synergy Aesthetics Sonoma is a medical spa at 660 Third Street West in Sonoma, California. It says it serves Petaluma, Napa, Sonoma and Sebastopol. Most of its menu is cosmetic, including microneedling, PRP, neurotoxins, dermal fillers, laser, IV hydration, PDO thread lift and a gummy smile treatment. This listing covers three of its services: medical weight loss management, bioidentical hormone replacement therapy (BHRT) and peptide therapy.

The weight loss program starts with a consultation and health review, then a custom plan that may include nutrition support, activity guidance and medication management, with ongoing visits. The medications it names are compounded Semaglutide and Tirzepatide. In its own words: "Medical weight loss is supervised by licensed professionals." BHRT starts with lab work to check hormone levels, and the practice may recommend pellets, creams, patches or injections. The two people named as prescribers are Mary Pat Nesbit, PA-C, who has more than 27 years of experience as a Physician Assistant, and Korina Tanner, MD.

This listing is for its Sonoma office at 660 Third Street West.

What does it cost?

It does not publish prices for weight loss, BHRT or peptide therapy, and it does not state a consultation fee. It does not say whether medication is included in any price. Its membership plans come in three tiers. The first is Tier 1 Essential, a basic monthly membership with benefits such as discounts, priority booking or a monthly treatment. Tier 3 Luxe adds benefits tied to its sister dental practice, Synergy Dental Group. No dollar amounts are shown for any membership. The payment options listed are cash, Cherry financing and credit cards, which carry a 3% charge. It does not say it accepts insurance, and it does not state membership cancellation terms.

What should you ask before you book?

Ask who will write the weight loss prescription, and which days Dr. Tanner sees patients at the Sonoma office. Ask whether any program fee includes compounded Semaglutide or Tirzepatide, or whether medication is billed separately. Ask whether Tirzepatide is compounded or brand-name, and what the consultation, lab work and follow-up visits cost. Ask who prescribes peptide therapy, since its description does not name anyone. Ask whether any visits can be done by video, because telehealth is not mentioned. Ask whether HSA or FSA cards are accepted, and how memberships renew and cancel.

The posted hours read as Monday and Friday 9am to 5pm, Tuesday through Thursday 4pm to 7pm, Saturday 10am to 2pm, and Sunday by appointment. The listing does not make each pairing clear, so confirm the schedule at 707-940-8742 before you visit.

Who is it a good fit for?

This is a good fit if you want a medical weight loss, BHRT or peptide program in a Sonoma office that also offers cosmetic treatments, and you are willing to get the price, medication and cancellation terms in writing before your first visit. If you need a posted price before you call, this clinic does not publish one.
